So, I was going to find some fap material tonight, and did a search for the "gangbang" tag.
There's a ton of threesomes tagged as gangbang.

I would like to point out for future reference for anyone tagging, a threesome is not a gangbang.
If you check the wiki page of gangbang for the definition, it is 3 or more characters having sex with a single other character.
Therefor the minimum character count for a pic to be tagged as a gangbang is 4.

I will be going through all the currently tagged pics to fix this, and then if I still have any effort left in me I'll attempt to find any pics that should be tagged as such, but are missing the gangbang tag.

Thanks.
